以太坊的市值是否会“翻转(Flipping)”超过比特币,是加密行业一直都在探讨问题。最近,去中心化金融(DeFi)的研究人员认为,“PoS”正是以太坊能够在未来取代比特币的经济基础与架构。
在了解什么是“PoS”之前,必须先了解区块链的运作方式。
区块链为一种分布式的网络结构 — — 点对点网络(P2P),不存在中央服务器。因此,区块链运用一系列的共识算法机制以取代中央管理者的工作,检查和更新在区块链上的交易账本。根据不同的运行特征,上述共识机制可进行不同的分类。下文仅介绍最常见的PoW和PoS。
PoW为Proof-of-Work的缩写,即“工作量证明”,这也是比特币的共识算法。一种通过算力的比拼来选取一个节点,之后,由该节点决定下一轮共识的区块内容的共识方式。简单来说,当比特币矿工们挖掘到一个新区块的时候,便需要对SHA-256(密码散列函数一种比特币采用的算法,特点为验证正确答案易,得到答案难)进行运算,直到找到正确的“答案”(也被称为“哈希值”)为止。而这一个过程,便是耳熟能详的比特币“挖矿”活动。
这样的方式,虽然很大程度上能够保障了内容的安全性,公平公正 — — 谁先得出的答案谁就能获得相应的利益,但以现在的计算机水平,要破解SHA-256需要消耗极大的资源。每一次的运算都需要强大的计算能力,但最终却只有一位用户能够脱颖而出,显然是一种浪费资源的方法。因此,专家们提出了一种新方法,试图解决比特币共识机制PoW的问题,并命名为PoS。
PoS为Proof of Stake,称作“股权证明机制”,通过计算用户占总币数的百分比和占有币数的时间来决定记账权。因此,当加密货币质押的数量越多、时间越长时,获得奖励的机会就越大。在PoS机制中,由于通过数量和时间来决定记账的节点,因此就不需要像PoW一样,通过强大的算力进行运算,不会造成资源浪费。
“PoW本质为算力竞争,而PoS的本质为金钱竞争。”
整体而言,虽然PoS弥补了PoW需要准备强大昂贵的采矿设施的缺点,但是由于其通过数量和时间来决定记账点的方式,导致富人大量囤积加密货币而获得更多的话语权的失衡可能——若是这些富人们联合起来,就能对区块链上的交易有着话语权,为“去中心化”带来威胁。
